Embodiment 1-3

[0108] The components given in Table 1 below were melted, mixed thoroughly with one another and pelletized from the melt. The average particle size of the granules is 5 mm. A 5% aqueous dispersion is then prepared from the granules thus obtained. The dispersion is applied to a weight per unit area of ​​15 g / m 2 SSS spunbonded nonwoven fabric made of polypropylene fibers. The coat weight was adjusted to 0.5%, based on the dry weight of the nonwoven.

Abstract

The invention relates to a composition for use for the permanent hydrophilic finishing of textile fibres and thus produced textile products, said composition comprising a hydrophilically modified or amphoteric polydimethylsiloxane in a proportion of 3 - 30 wt.%; a quaternary ammonium compound in a proportion of 25 - 85 wt.%, said quaternary ammonium compound has a melting point of at least 55 degrees; a fatty alcohol having a melting point of at least 60 degrees in a proportion of 0 - 25 wt.%; a non-ionic consistency regulator in a proportion of 0 - 40 wt.%, and at least one dispersing agent in a proportion of 0 - 10 wt.%. Said composition is preferably in the from of granulates and has a melting point of at least 45 degrees.

Description

technical field [0001] The present invention relates to a composition for the permanent hydrophilic finishing of textile fibers and textile articles made therefrom, such as nonwovens (nonwovens). Background technique [0002] Various methods are available for producing nonwoven fabrics. In forming spunbond nonwoven fabrics by spunbonding or meltblowing, filaments formed from extruded polymers by melt spinning are extruded through spinning nozzles under high pressure, drawn in a stream of hot or cold air Stretching and laying (ablegen) non-woven fabrics. Nonwovens can be subsequently cured chemically, mechanically or thermally. In the production of dry-laid nonwovens, chopped fibers are used, which are first carded to form a fiber fluff and then chemically, mechanically or thermally cured. [0003] Hydrophilic nonwovens are used in particular as cover webs or as intermediate webs for hygiene articles such as baby diapers, feminine hygiene napkins, incontinence products and...
